Koehler, Jr., Midlothian, Ill.,assignor to Continental Can Company, Inc., New York, N.Y., a corporationof New York Filed May 15, 1964, Ser. No. 367,804 13 Claims. (Cl. 22288)This invention relates to a novel bayonet spout for opening motor oilcans and is particularly characterized in the provision of an invertedblade constructed to prevent the piercing of the can body during theopening thereof yet insures a tight fit with minimum leakage, andsimultaneously provides ease of removal of the bayonet spout after thecontents of the can have been dispensed.

It is an object of this invention to provide a novel bayonet spoutparticularly adapted for opening motor oil cans having composite bodywalls, the spout including a spout body of a generally tubularconstruction having an outlet end portion and an inlet end portion, aguide shield extending beyond the inlet end portion, a piercing portionoverlying the guide shield, the piercing portion having a piercing pointdirected away from the end portion of the spout body, and the piercingportion including a cutting edge sloping from the piercing point towardthe guide shield and terminating closely adjacent thereto therebyspacing the piercing point a substantial distance from the guide shieldand generally preventing the piercing of a composite body wall of amotor oil can to which the bayonet spout is attached.

A further object of this invention is to provide a novel bayonet spoutof the type just described in which the piercing portion includes meansfor insuring a tight fit with a minimum of leakage when the bayonetspout is properly seated upon and secured to the oil can, and further.including means for readily and unobstructively withdrawing the piercingportion from an opening in an end wall of the can to which the spout hasbeen seated.

A further object of this invention is to provide a novel bayonet spoutincluding a spout body of a generally tubular construction having anoutlet end portion and an inlet end portion, a guide shield extendingbeyond the inlet end portion and underlying a piercing blade similarlyprojecting beyond the inlet end portion of the spout body, the bladebeing of a generally inverted U-shaped configuration, a bight wallportion of the blade terminating in a piercing point directed away fromthe inlet end portion of the spout body and spaced a substantialdistance above the guide shield, and side wall portions of the invertedU-shaped blade being impressed inwardly to permit the ready andunobstructive withdrawal of the blade from an opening in an end wall ofa can into which the bayonet spout has been once seated.

A further object of this invention is to provide a novel bayonet spout0f the type described above and including channel means to either sideof the side walls of the blade and an opening in the bight wall thereofwhereupon free flow of liquid from the can through the spout body duringa delivery operation is achieved.

Still another object of this invention is to provide a novel bayonetspout of the type described above including stop means for accuratelypositioning and locating the bayonet spout relative to a can with whichthe spout is associated, and the bight wall or bight portion of theblade having a shallow convergent angle relative to the guide shield forassuring a tight fit between the bayonet spout and the associated can.

A further object of this invention is to provide a novel bayonet spoutas described above and including a high capacity overflow cup at theinlet end portion of the spout body which is cooperative with thechannels to prevent oil spillage at such times as the bayonet spout isnot fully seated upon the associated can.

With the above and other objects in view that will here inafter appear,the nature of the invention will be more clearly understood by referenceto the following detailed description, the appended claims and theseveral views illustrated in the accompanying drawing.

In the drawing:

FIGURE 4 is a fragmentary view taken along line 4-4 of FIGURE 2, andillustrates an opening in a bight portion of the wall for deliveringliquid from the can therethrough during a delivery operation.

FIGURE 5 is a fragmentary sectional view taken along line 55 of FIGURE2, and clearly illustrates impressions in the side walls of the bladeportion for facilitating tight sealing engagement between the 'blade andthe opening formed in the can end wall.

A novel bayonet spout constructed in accordance with this invention isgenerally designated by the reference numeral and comprises a spout body11 which is preferably constructed from an upper body portion 12 and alower body portion 13 secured together by substantially identicaldiametrically opposite longitudinal seams 14. The spout body 11 of thebayonet spout 10 includes an outlet end portion 15 and an inlet endportion 16.

Side Walls 17 and 18 of the inlet end portion 16 flare away from eachother (FIGURES 3 and 4) to define with a similarly flaring top wall 20 ahigh capacity overflow cup portion 21 (FIGURE 1) which functions in aconventional manner to insure against oil or similar liquid spillagewhen the bayonet spout 10 is not fully seated upon or secured to a can Cin a manner to be described more fully hereafter.

Each of the walls 17 and 18 is provided with an identical slot 22(FIGURES 1 and 2), contoured to the general cross-sectionalconfiguration of a seam S securing an end wall or panel B of the can orcontainer C to the body B thereof (FIGURE 2). The slots 22 receive andengage the seam S in a manner clearly illustrated in FIGURE 2 to formstop means which limit the entry of a blade or piercing portion 23 intothe can C, as is illustrated .in FIGURE 2 of the drawing. A shallow,generally concave guide shield 24 projects endwise from the inlet endportion 16 a distance corresponding to the end'wise projection of theblade portion 23. The guide shield 24 is contoured generally to thecross-sectional configuration of the can body B, as is best illustratedin FIGURE 5 of the drawing.

The blade or piercing portion 23 is of a generally inverted U-shapedcross-sectional configuration (FIGURE 5) and includes a bight portion orwall 25 and a pair of side walls or legs 27 and 28. The side walls 27and 28 include respective cutting edges 30 and 31 which slope graduallyfrom a piercing point 32 of the blade 23 toward the guide shield 24 atthe inlet end portion 16 of the 3 bayonet spout 10, as is bestillustrated in FIGURE 2 of the drawing with respect to the side wall 28.

Substantially midway between the piercing point 32 of the blade 23 andan opposite end portion 33 thereof secured to the overflow cup portion21 by a bolt 34 and an elongated nut 35, the side walls 27 and 28 aredepressed or recessed inwardly toward each other (FIG- URES 3-5) todefine central wall portions 37 and 38 respectively which open concavelyaway from each other. The recessing of the portions 37 and 38 of therespective side walls 27 and 28 allow the blade 23 to be easily andreadily removed from an opening (FIGURE 2) in the end wall E of the canC.

The blade portion 23 of the bayonet spout 10 is provided with asubstantially rectangular opening 40 (FIG- URES 3 and 4) formed in thebight portion 25 thereof. The opening 40 is partially defined byidentical cut-away portions 41 in each of the side walls 27 and 28, asis best illustrated in FIGURE 2 of the drawing. The opening 40,including the cut-away portions 41, permits the rapid flow of liquid,such as oil, in the interior of the can C through the blade portion 23and into the inlet end portion 16 of the spout body 11.

In addition to the rapid flow of liquid through the opening 40 in themanner just described, the blade portion 23 of the bayonet spout 10 isprovided with channel means 47 and 48 to either side of the bladeportion 23 at the opposite end portion 33 thereof. As is bestillustrated in FIGURES 3 and of the drawing, the channel means 47 liesbetween the side wall 17 of the inlet end portion 16 of the spout body11 and a connecting web portion 50 of the blade side wall 27 lyingbetween the impressed side wall portion 37 and the end portion 33. Thechannel 48 is similarly defined between the side wall 18 of the inletend portion 16 and a similar web 51 of the blade side wall 28 betweenthe impressed side wall portion 38 and the opposite end portion 33. Thechannels 47 and 48 thus direct any liquid which leaks be tween theopening 0 in the end wall E of the can C and the webs 50 and 51 directlyinto and through the inlet end portion 16 of the bayonet spout 10. If,for any reason, the bayonet spout is not fully seated upon the can C orthe opening 0 is irregular or deformed, any surplus liquid which tendsto accumulate in the overfl'ow cup portion 21 (FIGURE 1) of the bayonetspout 10 is directed into the tubular body 11 thereof through thechannel means 47 and 48, thus insuring against spill-age when the spout10 is not fully seated upon the can C.

During a typical operation or use of the bayonet spout 10, the guideshield 24 is positioned adjacent to or in contact with the seam S of thecan C after which downward force, as viewed in FIGURES l and 2 of thedrawings is applied to the tubular body 1 1 of the spout 10 to force thepiercing point 32 into the end wall E.

' It should be particularly noted that the piercing point 32 pierces theend wall E of the can C at a point remote from the seam S. This piercingof the end wall E is extremely desirable in the case of cans having bodywalls, similar to the body wall B which are of a composite constructioni.e., paperstock or similar material lined with aluminum, plastic orother fluid-tight materials. Such composite body walls tend to bepierced by the piercing points of conventional bayonet spouts which arepositioned closely adjacent conventional guide shields, such as theguide shield 24 of this invention. However, the substantial spacingbetween the piercing point 32 and the guide shield 24 of the bayonetspout 10 substantially precludes the inadvertent or accidental piercingof the body wall B during the entry of the blade 23 into the interior ofthe can C.

As the bayonet spout 10 is further introduced into the interior of thecan C, the cutting edges 30 and 31 of the blade side Walls 27 and 28,respectively, sever the end wall E to form the opening 0 and urge thematerial M removed therefrom toward the body wall B of the can C. Theinsertion of the blade 23 into the interior of the can C continues untilthe overflow cup portion 21 is seated against the end wall E (FIGURES 1and 2) and the seam S of the can C is received in each of the slots 22of the side walls 17 and 18.

The can C is inverted from the position thereof illustrated in FIGURES 1and 2 of the drawing to deliver the liquid (not shown) such as oil, inthe can C through the spout body 11 and the outlet end portion 15 in amanner well known in the art. After the delivery operation is completed,the can C is again positioned as shown in FIGURES 1 and 2 and force isapplied to the spout body 11 to withdraw the same upwardly as viewed inFIGURES 1 and 2 of the drawing. The withdrawal of the bayonet spout 10is facilitated by the impressed portions 37 and 38 of the respectiveblade side walls 27 and 28 which, in effect, converge toward each otheraway from the web portions 50 and 51 to ease the withdrawal of the blade23 outwardly of the opening 0. During this withdrawal the removedmaterial M ceases to bear against the side wall edges 30 and 31 of theblade 23 to also ease in the withdrawal or removal of the blade 23 fromthe can C.

In addition to the noted construction of the side walls 27 and 28 of theblade 23 to allow the easy removal of the blade from the can C, thebight portion or wall 25 of the blade 23 is also inclined slightly at anangle no greater than 5 degrees toward the guide shield 24 in adirection away from the inlet end 16 of the spout body 11, as is bestillustrated in FIGURE 2 of the drawing. This angle of inclination A ofthe blade 23 assures a progressively tighter fit the deeper the blade 23is inserted in the can C and consequently a relatively easier withdrawalthe more the blade spout 10 is withdrawn from the can C.

At this time, it is pointed out that if it is so desired, in lieu of theelements 34 and 35 securing the blade 23 to the spout body 11, the blade23 can be constructed as an integral part of the member 12. Theoperation of the bayonet spout would, however, remain substantially thesame upon such a reconstruction as that heretofore described in theconsideration of the bayonet spout 10.

From the foregoing, it will be apparent that the bayonet spout disclosedherein will operate to properly open cans without piercing the bodywalls thereof, permit the rapid delivery of liquid therefrom andfacilitates the ease of removal of the spout from a can to which thesame is secured.

From the foregoing, it is believed apparent that novel and advantageousprovision has been made for carrying out the desired end. However,attention is directed to the fact that other variations may be made inthe example pouring spout disclosed herein without departing from thespirit and scope of the invention as defined in the appended claims.
